Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below through specific embodiments and with reference to the accompanying drawings.

[0053] Existing video summary generation technology can realize the concentration of the original video content, and can splicing and combining the video content of different targets in different time periods under the same video background into a common background image. The simple mixing of target objects in the time period may cause confusion in the summary image, which is not conducive to quick browsing and locking of target objects. In addition, since there is no direct relationship between the target objects in the video summary and the original video, users need to Manually locating the target object in the original video also leads to difficult positioning and low retrieval efficiency.

[0054] The purpose of the present invention is...

Abstract

The invention provides a video abstract generation and video backtracking method and system. According to the method, moving objects in an original video are separated, the separated moving objects are identified and classified, and a highly concentrated video abstract file with compact content is generated with a scalable image fusion technology and a multi-mode information fusion method. During video backtracking, firstly, the number and types of the objects appearing in a video image are elastically controlled according to the number of the objects appearing in the image selected by a user as well as an object which the user is interested in. When the user clicks one object in the image, the system can quickly backtrack the original video on a server and present the whole appearing process of the object to the user.

Description

technical field [0001] The present invention relates to the field of video surveillance, in particular to a method and system for generating video summaries and video backtracking. Background technique [0002] In the field of storage, with the rapid development of society, people are getting stronger and stronger for security protection, and at the same time, the demand is also increasing. Continuous improvement. As a carrier in the field of security protection, video surveillance recordings can allow people to review and restore what happened in the past more effectively. However, video recordings store a large amount of data and a long storage time. Searching for events that occurred in a certain past time through recordings It is very time-consuming when people, cars or certain events are involved, which greatly increases manpower and material resources. In order to quickly and efficiently browse these video surveillance recordings, video summarization technology is pa...
